Where does diffusion occur in fish?
Fish use diffusion and osmosis to keep their tissue healthy. Diffusion starts in the gills and for some small molecules can happen in the gut walls as well.
Why is diffusion important to animals?
Because diffusion is how chemicals travel in and out of the animal's cells. If diffusion didn't occur then the animal would die.
What is the difference between passive diffusion and facilitated diffusion?
Passive diffusion is what naturally happens without any assistance of any sort. Facilitated diffusion requires extra energy from extra sources to happen.
What drives diffusion?
Diffusion is the movement of ions and other micro molecules across a barrier or membrane. Diffusion is caused by gradients on either side of the membrane.
How does the rate of diffusion in a gelatin at room temperature compare with the rate of diffusion in water at the same temperature?
The rate of diffusion in gelatin at room temperature is very slow. This is especially compared to the rate of diffusion in water at the same temperature.
Does diffusion require help from vesicles?
No, Diffusion requires transport proteins.
What is is called when vesicles are used to move substances out of the cell?
The process that requires transport vesicles to transfer material out of a cell is called exocytosis.
What are capillary transport mechanism?
diffusion through the membranes bulk flow transport via vesicles or caveolae
What moves substances around or out of the cell?
Vacuoles, also called cytoplasmic vesicles. The Golgi Apparatus prepares and processes cytoplasmic vesicles for Cellular Export of translated proteins; cytoplasmic vesicles such as lysosomes, peroxisomes and proteosomes deal with the internal processing of cytoplasmic components.
Why is endocytosis use for?
it is used for vesicles
Does exocytosis use vesicles?
Yes.
What is a process by which cells release their contents?
Exocytosis is the process by which cells release their contents in form of vesicles. This may also happen due to diffusion.
What is the use of carrier proteins for diffusion?
facilitated diffusion.
Is endocytosis an example of diffusion?
Endocytosis is NOT an example of diffusion. It is an example of active transport whereas diffusion is a type of passive transport. The difference lies in the fact that diffusion does not require energy to take place, and endocytosis does.
In which process does the cell use a vesicles to move molecule out?
Exocytosis
How do cnidarians breathe?
They use diffusion to get air through there body walls.
What the function of secretory vesicles?
Vesicles perform many functions through complex mechanisms that can involve many aspects of cell regulation. Secretory vesicles in particular are specialized vesicles formed in the trans-golgi apparatus for releasing a product (such as molecule or protein) outside the cell. Secretory vesicles are used for exocytosis. Mast cells use secretory vesicles to release histamine which is a molecule involved immune response. Neurotransmitters can also be transmitted in secretory vesicles from nerve cells.
